Study of wear mechanisms of cemented carbide tools during machining of single-phase niobium

In particle accelerator facilities, single-phase niobium is used in superconducting accelerator components. Machining induced surface quality of such components is strongly connected to the functionality of accelerators. In this study, tool wear development and its influence on the surface quality of Nb workpiece have been investigated in longitudinal turning.

Impact of coordinate rotation on eddy covariance fluxes at complex sites

The choice of coordinate system to calculate eddy covariance fluxes becomes particularly relevant at complex measurement sites. The traditional way is to perform double rotation (DR) of the coordinate system i.e., to calculate turbulent fluxes in a coordinate system that is aligned with the flow streamlines within the flux averaging period (e.g., Kaimal and Finnigan, 1994). The second approach, th

Effects of change of density stratification due to Isahaya Sea-Dyke on the fate of anoxic water in the Ariake Sea

In this study, we aim to investigate the possibility that the construction of the Isahaya Sea-Dyke significantly causes anoxic water development in the bottom layer in the Ariake Sea, Japan. We numerically compared the vertical distribution of dissolved oxygen (DO) in the water column between two cases with the dyke and without it. As a result of this research, the followings are clarified: 1) DO

Covalent Functionalization of Bioengineered Polyhydroxyalkanoate Spheres Directed by Specific Protein-Protein Interactions

Bioengineered polyhydroxyalkanoate (PHA) spheres assembled in engineered bacteria are showing promising potential in protein immobilization for high-value applications. Here, we have designed innovative streamlined approaches to add functional proteins from complex mixtures (e.g., without prior purification) to bioengineered PHA spheres directly harnessing the specificity of the SpyTag/SpyCatcher

How violence happens (or not)

Objective: Recent studies show that violence is difficult to accomplish and only occurs under particular situational circumstances—but does this also apply to protests in authoritarian regimes? This article investigates the microdynamics of violence during the antiregime protests in Tunisia, Syria, and Bahrain. Method: The argument is based on visual data analysis of video footage of violent and n

Routing using Safe Reinforcement Learning

The ever increasing number of connected devices has lead to a metoric rise in the amount data to be processed. This has caused computation to be moved to the edge of the cloud increasing the importance of efficiency in the whole of cloud. The use of this fog computing for time-critical control applications is on the rise and requires robust guarantees on transmission times of the packets in the ne

Decreasing organic carbon bioreactivity in European rivers

European rivers experience increased loading of total organic carbon (TOC) from terrestrial sources due to factors involving changes in land use, climate and soil acidity. However, little is known about how increased TOC is linked to changes in the bioreactivity of organic matter in these rivers on a continental scale. We compiled paired measurements of TOC and biological oxygen demand in 5‐day 20

Interactions between University Spin-Offs and Academia : A Dynamic Perspective

Purpose: This paper aims to investigate the nature and dynamics of the interaction between university spin-offs (USOs) and academia. Design/methodology/approach: The theoretical framework is grounded in an interactive view based on the industrial marketing and purchasing literature on USOs and their development. The concepts of activity links, resource ties and actor bonds are used as a starting p

Dogs can sense weak thermal radiation

The dog rhinarium (naked and often moist skin on the nose-tip) is prominent and richly innervated, suggesting a sensory function. Compared to nose-tips of herbivorous artio- and perissodactyla, carnivoran rhinaria are considerably colder. We hypothesized that this coldness makes the dog rhinarium particularly sensitive to radiating heat. We trained three dogs to distinguish between two distant obj

Effects of Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) in the Treatment of Goblet Cell Carcinoma : A Prospective Cohort Study

BACKGROUND: Goblet cell carcinoma (GCC) of the appendix is a rare disease. Treatment options vary according to disease staging. Cytoreductive surgery in combination with hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) may improve survival in patients with peritoneal spreading.OBJECTIVE: The aim of this study was to examine the prognosis of patients with appendiceal GCC treated per protocol

Survival of patients with colorectal peritoneal metastases is affected by treatment disparities among hospitals of diagnosis : A nationwide population-based study

BACKGROUND: In the Netherlands, surgery for peritoneal metastases of colorectal cancer (PMCRC) is centralised, whereas PMCRC is diagnosed in all hospitals. This study assessed whether hospital of diagnosis affects treatment selection and overall survival (OS).METHODS: Between 2005 and 2015, all patients with synchronous PMCRC without systemic metastases were selected from the Netherlands Cancer Re

Randomized trial of cytoreduction and hyperthermic intraperitoneal chemotherapy versus systemic chemotherapy and palliative surgery in patients with peritoneal carcinomatosis of colorectal cancer

PURPOSE: To confirm the findings from uncontrolled studies that aggressive cytoreduction in combination with hyperthermic intraperitoneal chemotherapy (HIPEC) is superior to standard treatment in patients with peritoneal carcinomatosis of colorectal cancer origin.PATIENTS AND METHODS: Between February 1998 and August 2001, 105 patients were randomly assigned to receive either standard treatment co

Determination of the event collision time with the ALICE detector at the LHC

Particle identification is an important feature of the ALICE detector at the LHC. In particular, for particle identification via the time-of-flight technique, the precise determination of the event collision time represents an important ingredient of the quality of the measurement. In this paper, the different methods used for such a measurement in ALICE by means of the T0 and the TOF detectors ar

Prompt and non-prompt J / ψ production and nuclear modification at mid-rapidity in p–Pb collisions at √sNN=5.02 TeV

A measurement of beauty hadron production at mid-rapidity in proton-lead collisions at a nucleon–nucleon centre-of-mass energy sNN=5.02 TeV is presented. The semi-inclusive decay channel of beauty hadrons into J / ψ is considered, where the J / ψ mesons are reconstructed in the dielectron decay channel at mid-rapidity down to transverse momenta of 1.3 GeV/c. The b b ¯ production cross section at m

Perioperative systemic chemotherapy in peritoneal carcinomatosis of lymph node positive colorectal cancer treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is the preferred treatment of peritoneal carcinomatosis (PC) of colorectal carcinoma. Patients with positive lymph node status have worse survival after CRS-HIPEC, which is probably due to higher rates of systemic failure. In this study, we analysed the effect of administration and timing of systemic chemot

Treatment of ovarian metastases of colorectal and appendiceal carcinoma in the era of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

AIM: To compare outcome of women with ovarian metastasis who underwent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) to outcome of women without ovarian metastasis who underwent CRS-HIPEC.METHODS: A prospective CRS-HIPEC database was searched to identify women with surgically treated colorectal carcinoma between 2000 and 2012. Patients with ovarian metastasis were

Morbidity associated with colostomy reversal after cytoreductive surgery and HIPEC

BACKGROUND: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has improved the survival in selected colorectal cancer patients with peritoneal metastases. In these patients, the risk of a low anastomosis is sometimes diminished through the creation of a colostomy. Currently, the morbidity and mortality associated with the reversal of the colostomy in this population
